BeschreibungMethyl pentanoate, commonly known as methyl valerate, is the methyl ester of pentanoic acid (valeric acid) with a fruity odor. Methyl pentanoate is commonly used in fragrances, beauty care, soap, laundry detergents at levels of 0.1 – 1 % . In a very pure form ( greater than 99.5 % ) it is used as a plasticizer in the manufacture of plastics. It is also used as an insecticide.

OccurrenceReported found in small amounts in the essential oil from the fruits of Ananas sativus Schult. Also reported present in apple, coffee, honey, kiwi, melon, papaya, pineapple, strawberry, tea, wine, blackberry, baked potato, olive, starfruit, passion fruit, soursop, Bourbon vanilla, mountain papaya and naranjilla fruit.

VerwendenMethyl valerate can be used:In the preparation of lankacidin C 8-valerate.As a reactant to synthesize bis(2,2,2-trifluoroethyl) 2-oxoalkylphosphonates.As a substrate in the fluorination reactions of unactivated C(sp3)H bonds using decatungstate photocatalyst and N-fluorobenzenesulfonimide.

Darstellung

synthetischeBy direct esterification of valeric acid with methanol in the presence of concentrated H2SO4. Note: This ester hydrolyzes readily
